Computer glitch delays JetBlue flights

Dozens of JetBlue Airways flights were delayed Friday morning after a computer failure limited the airline’s ability to dispatch planes.

The system was restored by 10:30 a.m. but the airline warned that delays will persist throughout the day.

At New York’s John F. Kennedy International Airport — JetBlue’s largest base of operations — about a third of all the airline’s flights were listed as “delayed” on the flight monitors. The typical delay was about 90 minutes.

The airline blamed “IT network connectivity issues” but did not elaborate. Spokesman Mike Miller said in an email that JetBlue’s system was being restored, but travelers should expect some flight delays throughout the day.

Computers are used to calculate weight, fuel and other key information needed before a plane can leave the gate.
